Hi @malikox,
Thanks for the post.
I suppose you could try hooking into the acf/save_post and then update the next row using the update_sub_field() function.
This will require some logic to check for the row numbers as selectors and then get the $new_value which will be populated via the said function.
For more info on this function, you can have a look at the following resource page: http://www.advancedcustomfields.com/resources/update_sub_field/
